This DNA kit is for kids, but might be fun for all ages (and for some potential projects). It says you can view and map real DNA, do experiments as well as extract DNA from vegetables. It comes with a Centrifuge, mixer, electrophoresis chamber and other parts to perform the tests. Some bad news for Canadians, two of the 10 experiments included in the kit require the “Lambda DNA” which does not ship to Canada. Link.
